In the first quarter, sales in the overall razor and blade category declined. For men's shaving systems, sales declined 3.6 percent in the last quarter. Energizer posted a 9 percent increase in the second fiscal quarter, as the company cut costs, but has lowered expectations for sales in the next quarter. This measured outlook is partially a response to pressure from promotions in the personal-care market.

P&G, which owns the Gillette shaving brand, has been offering more deals, increasing promotion by 5 percent in the quarter. Last year, P&G cut razor prices in order to recapture market share.

"By our estimation," Klein said, "our competitor's total [advertising and promotion] spend rate against razors and blades during the last nine months has increased measurably, with no material benefit to the category growth or relative market share positions."

A P&G spokesman, Paul Fox, countered, "The U.S. blade and razor category is growing." He added that the company's level of promotion is about the same as Energizer's.
